Voters look at a list of provisional results at a polling station in Addis Ababa, after Sunday's third election in Ethiopia's 3,000-year history

Ethiopia's main opposition group has accused the ruling party of trying to cling to power, after claiming election victory while votes were still being counted.

Berhanu Nega of the opposition Coalition for Unity and Democracy Tuesday told reporters that Monday's announcement was a clear sign that Ethiopia's ruling party, the Ethiopian People's Revolutionary Democratic Front, is using illegal means to keep its grip on power.

He also said results from Sunday's poll so far show his coalition has won at least 92 seats in the 547-seat federal parliament. An official vote count is to be released on June 8.

The European Union has asked both sides to wait for official results before declaring victory.

E.U. observers say the poll was orderly, but they noted some cases of voter intimidation against opposition supporters, including several election-related murders.
